- [4u202f+u202f1] Cyclization of benzohydrazide and ClCF2COONa towards 1,3,4-oxadiazoles and 1,3,4-oxadiazoles-d5
-
A facile synthesis of 1,3,4-oxadiazoles and 1,3,4-oxadiazoles-d5 via [4 + 1] cyclization of ClCF2COONa with non-amine compounds containing amino groups is developed. Of note, this is the first time that halofluorinated compounds are used as C1 synthon to construct deuterated nitrogen-heterocyclic compounds. The current protocol features simple operation, readily accessible raw materials, wide substrate scope and valuable products

- Electrophilic activation of nitroalkanes in efficient synthesis of 1,3,4-oxadiazoles
-
A novel methodology for general and chemoselective preparation of non-symmetric 1,3,4-oxadiazoles is developed. This unusual reaction proceeds via polyphosphoric acid-assisted activation of nitroalkanes towards nucleophilic attack with acylhydrazides.

- Design, synthesis and biological evaluation of 2-(phenoxymethyl)-5-phenyl-1,3,4-oxadiazole derivatives as anti-breast cancer agents
-
Structural based molecular docking approach revealed the findings of 2-(phenoxymethyl) -5-phenyl-1,3,4-oxadiazole derivatives. The compounds (7a-o) were synthesized and characterized well by using conventional methods. The compounds, 7b and 7m were reconfirmed through single crystal XRD analysis. The synthesized compounds (7a-o) were evaluated their antiproliferative activities against MCF-7 and MDA-MB-453. Furthermore, Lipinski's rule of five and pharmacokinetic properties were predicted for the test compounds. These results demonstrate that the compounds 7b and 7d exhibit more potent cytotoxicity and 7d exhibits dose-dependent activity and reduced cell viability. Further, the mechanism of action for the induced apoptosis was observed through morphological changes and western blotting analysis. These findings may furnish the lead for further development.

- Design and synthesis of tailored human caseinolytic protease P inhibitors
-
Human caseinolytic protease P (hClpP) is important for degradation of misfolded proteins in the mitochondrial unfolded protein response. We here introduce tailored hClpP inhibitors that utilize a steric discrimination in their core naphthofuran scaffold to selectively address the human enzyme. This novel inhibitor generation exhibited superior activity compared to previously introduced beta-lactones, optimized for bacterial ClpP. Further insights into the bioactivity and binding to cellular targets were obtained via chemical proteomics as well as proliferation- and migration studies in cancer cells.

- BICYCLIC HETEROARYL COMPOUNDS AS PDE10 INHIBITORS
-
The invention pertains to tricyclic heteraaryi compounds that serve as effective phosphodiesterase (PDE) inhibitors. The invention also relates to compounds which are selective inhibitors of PDE 10. The invention further relates to pharmaceutical compositions comprising such compounds; and the use of such compounds in methods for treating certain central nervous system (CNS) or other disorders. The invention relates also to methods for treating neurodegenerative and psychiatric disorders, for example psychosis and disorders comprising deficient cognition as a symptom.
